Well, at first, like most people think, I also think it was a revenge drama, but when they got the body swap, I was already intrigued, like, how is he going to take revenge on himself?

But the plot is even better; instead of revenge, it was a journey to redeem himself, a second chance in life to sort everything back. I admit it was slow and has lots of boring stuff, but believe me, the betrayals and massive plot twist will keep you watching.
It is a very sad drama, actually, and it makes me realise a lot of things about my family that I also didn't realise before.

It's important to note that some might find it disturbing seeing the daughter started having feelings for her father in the younger body, but the director is very wise and keeps the romance in check; her father is still deeply in love with her mother, and his love for his daughter is just fatherly love.

I won't give away the ending, but it's a happy one in which everyone who commits a crime is held responsible for their actions; the true villain is your assumption of someone.
